Apple's iPhone 4 has a good-quality camera module for its size, one that includes a backlit sensor and small autofocus mechanism. Thanks to various applications available for the iPhone 4, it can come in surprisingly handy, and sharing your photos is easier than on most pocket cameras.

With a higher-resolution 8-megapixel backlit sensor, a faster processor, and all the photography apps you can imagine, the Apple iPhone 4S is an incremental improvement in color and low-light performance, and offers a minor increase in measured resolution.
